IMPROVEMENT IN RAILROAD-CHAIRS.

Specification forming part of Letters Patent No. L14,41 5 5, dated September 27, 1864.

To all whom it may concern:

Be it known that I, AMos RANK, of Salem, county of Columbiana, State ot' Ohio, have invented a new and Improved Railroad-Rail Chair; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specitication, in which- Figure l is a ltop view showing my chair applied at the joint of two sections of railroadrails. Fig. 2 is a side view of Fig. l. Fig. 3 is a bottom view of Figs. l and 2. Fig. 4 is a. central section of the two parts of the chair and views of the rail, wedge, and key. Fig. 5 is a central section taken vertically and transversely through the chair when secured to a rail. Fig. 6 is a longitudinal section taken in a vertical plane through Figsl, 2, 3, and 5.

Similar letters of reference indicate correspondin g parts in the several figures.

g The object of my invention is to so construct a two-part railroad-rail chair, having cheeks for supporting the rail-head ou each side, that the base of one part ot this chair shall interlock and break joints with the base of the opposite part thereof, thus affording a lirm and `substantial base-support for the rail at the joints, as will be hereinafter described.

Another object of my invention is to construct a two-part double-cheek rail-chair, which,when properly secured down in place at the joints of rails, shall support the same at the base, at the web or neck, and also at the lips of the railhead, said supports being so formed or applied that they shall all break joints with thc rail-joint, as will be hereinafter Y described.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

In the accompanying drawings, A A represent the ends of two sections of railroad-rails, which have notches a, cut horizontally through their webs to receive a iia-t bolt, b. These notches, when the ends ofthe rails are brought together, form a slot,which is somewhat longer than the width of the dat bolt b, and thus provision is made for the longitudinal expansion and contraction ofthe rails.

B B represent the sections of my twopart chair. These sections are each cast or otherwise formed with a cheek, d, which is curved in such manner as to conform to the sides of the rail and tol support the lips of the railhead, as shown in Figs. 2 and 5. The base plate of each section projects out from both sides of the cheeks el, and those portions of said plates which are lettered c c are perforated to receive the hold-down spikes that secure the whole down on the cross-ties, while those portions projecting from the opposite sides of their respective cheeks are intended to serve as supports for the base of the rail. These latter portions of the chair are constructed as follows: That portion of the chair lettered B has a tongue, g, formed on it, which,

when the two parts of the chair are brought together, fits into a recess formed between the two tongues gg, projecting from the part B', and thus we have an interlocking or lappingjoint. The tongue gis at an intermediate point between the ends ot' the chair, and eX- tends across the base of the rail, directly under the joint thereof. The tongues g g are ofthe same length as the central tongue, and these support the rail on each side otits joint. By this inode of constructing a chair it will be seen that I obtain all the advantages of a solid base directly beneath the railjoint, and

at the same time avoid the objections to the solid or single double-cheek chair. My chair s can be readily applied to or removed from arail without moving the sections thereof out ofline or loosening other parts of a rail-section for this purpose.

Another advantage which my two-part chair possesses over the common chair is that the interl )cking joints break joints with thejoiut ofthe rail, and when the two portionsB B are spiked down there will be no longitudinal thrust ot' onc of these portions without the other, and as each one ot these portions hrs a very wide base liability ofthe canting of the rail will be to a great degree obviated.

I employ as a means for securing the two parts ofthe chair to the sides of the rail,irre spective of the spikes which are driven through the outer portions of the chair base, a flat bolt, Z1, above referred to, which also breaks joints with the rail-joint and serves as au additional security against. the loosening of the rails. The head of this bolt is countersunk into the cheek of the portion B, and the iiat shank of this bolt passes laterally through the rail and opposite cheek and receives through its projecting end a wedge-pin, h, l laterally-holding bolt, b,passing through the .which passes down vertically into a hole in neck ofthe rail,'substautially as described.

this latter cheek, thus drawing together and 2.
